RAD ETX-2 devices can be ordered in different hardware flavors (ETX203AM,
ETX203AX, ETX205A, and ETX220A). Table 1
of the data sheet provides further information on the capabilities offered by each flavor.
Looking at all of the options can be overwhelming so we have created this ETX-2 selection assistance tool
MARKET SEGMENTS AND APPLICATIONS
ETX-2 is ideal for carriers, service providers, wholesale providers, and mobile operators seeking to offer unified SLA-based Ethernet business services, such as Ethernet Private Line (EPL), Ethernet Virtual Private Line (EVPL), and bridged E-LAN for enterprise and carrier-to-carrier applications as well as mobile backhauling applications.
NETWORK TOPOLOGIES AND INTEROPERABILITY
ETX-2 supports several network topologies such as linear, daisy chain, and self-healing rings (G.8032v2), working opposite ETX-5 or third-party Ethernet devices.
CARRIER ETHERNET 2.0
ETX-2 incorporates a complete set of CE 2.0-certified Ethernet service tools that allow the service provider to distinguish between high- and low-priority traffic, and to optimize TCP sessions.
ETX-2 provides two-rate three-color policers, and delivers true multi-CoS with hierarchical traffic management. Additionally, it supports advanced scheduling, WRED per CoS, shaping per EVC, and flexible classification rules.
ETX-2 delivers E-Line (EVL, EVPL), E-LAN (EPLAN, EVPLAN), and E-Tree (EP-TREE, EVP-TREE) services.
End-To-End Service Assurance with the ETX-2
ETX-2 provides wire-speed Ethernet OAM with delay measurements at line rate. Furthermore ETX-2 offers service activation tools such as
RAD ETX-2 Layer-2 Control Processing Features
ETX-2 can be configured to forward Layer-2 control frames (including other vendors L2CP frames), with optional MAC change, across the network or to peer supported protocols (IEEE 802.3 2005 and LACP), or to discard the L2CP frames.
ETX-2 features a wire-speed router with Virtual Routing Instances (VRF), allowing service providers to deploy L2 and L3
ETHERNET OVER PDH
ETX-2 transports Ethernet over PDH infrastructure via the following NG-PDH technologies:
Generic Framing Procedure (GFP G.7041)
GFP o PDH (G.8040)
PDH Virtual Concatenation (VCAT G.7043)
Link Capacity Adjustment Scheme (VCAT G.7042).
NG-PDH solutions improve overall network availability by reducing latency and optimizing line utilization and throughput.
Integrated management of MiRICi and MiTOP smart SFPs provides TDM (E1/T1/E3/T3/ OC-3/STM-1) connectivity over PDH or SDH legacy networks.
E1 / T1 PSEUDOWIRE OPTIONS of the ETX-2
ETX-2 provides E1/T1 pseudowire (PW) services via 4 or 8 integrated interfaces, as well as via a smart SFP (MiTOP). The PWs can be encapsulated using CESoPSN per IETF RFC 5086 or SAToP per IETF RFC 4553. The PWs are transmitted over IP networks or L2 networks with UDP/IP or MEF-8 encapsulation.
ETX-2 offers fast protection for virtually any kind of failure and in any linear, ring, or dual-homed topology. The device employs IEEE 802.3ad link aggregation (LAG), ITU-T G.8032v2 Ethernet ring protection, and ITU-T G.8031 Ethernet linear protection to ensure continuous availability and sub-50ms restoration in the event of network outages.
ETX-2 TIMING AND SYNCHRONIZATION
ETX-2 incorporates RADs advanced SyncTop synchronization and timing over packet feature set to support mobile heterogeneous network (HetNet) topology.
The ETX-2 device combines Synchronous Ethernet (SyncE) per ITU-T G.8261-G.8264 with IEEE 1588v2 Precision Time Protocol for cost-effective synchronization of frequency and phase.
ETX-2 provides RADs Distributed GMTM, a distributed 1588v2 Grandmaster with integrated GPS receiver that allows mobile operators and service providers to provide a high level of frequency and phase accuracy for LTE-A. The device also supports 1588v2 slave clock, boundary clock (BC), and transparent clock (TC).
MANAGEMENT AND SECURITY
The device can be managed via RADview, RADs carrier-class NMS for Windows and Unix, or any SNMP-based management system. ETX-2 supports a variety of access protocols, including CLI over Telnet, SNMPv3, and TFTP.
Security features include SNMPv3, RADIUS (client authentication), TACACS+ (client authentication, authorization, and accounting), SSH, and SFTP.
Access Control Lists (ACL) can also be used to flexibly filter and mark management traffic, enabling service providers to maintain network security by dropping unwanted packets.
MONITORING AND DIAGNOSTICS
Featuring ultra-fast, hardware-powered processing, ETX-2 performs monitoring and diagnostics at high scale and with maximum precision. End-to-end connectivity OAM (IEEE 802.1ag) as well as single-segment OAM (IEEE 802.3-2005) ensure flow-level fault management and performance monitoring, accurate SLA reports, L2 and L3 loopbacks at wire speed, and fast detection of failures for robust protection.
The Performance Management Portal is an SLA assurance system that is part of the RADview management system, enabling real-time monitoring of Ethernet service performance by collecting KPI data from RAD devices.
Digital Diagnostics Monitoring
ETX-2 supports digital diagnostics monitoring (DDM) SFP functions according to SFF-8472, excluding external DDM calibration.
